Curious to know if this is something that's still being pursued or
should I write my own layouting engine?
Thanks,

I am proposing an enhancement of Intl.Segmenter API (adding line
break support) to TC39 for ECMA402 (see
https://github.com/tc39-transfer/proposal-intl-segmenter-v2 ) The
API expose "line break opportunity" of text which implement the
Unicode® Standard Annex #14
<https://github.com/w3c/css-houdini-drafts/issues/14> UNICODE LINE
BREAKING ALGORITHM (see https://www.unicode.org/reports/tr14/)
so it can be used for developer to use it with
1. multiple lines of text rendering in <CANVAS>
2. jsPDF and other context which need to layout text into
multiple lines
3. SVG multiple lines of text
During the stage advancement discussion, one delegate suggest me
to reach out to Houdini to see which one of the following is better
1. Instead of adding that to ECMA402 as a low level API, leave
that part of job (breaking text into multiple lines of text)
to Houdini to add such API to empower developers to use it on
<CANVAS>, SVG , or for jsPDF and therefore there are no need
to add them into ECMA402, OR
2. TC39 add such low level API into ECMA402 to allow developers
to use that with the currently defined Houdini APIs, OR
3. TC39 add such low level API into ECMA402 to allow Houdini to
depends on Intl.Segmenter for the job of finding out
linguistic line break opportunity.
Please comment so we can move forward better in TC39 / ECMA402. Thanks
Similar question to you- do you think the enhancement to
Intl.Segmenter will be conflict or redundant to your API? or will
it complement the API you intend to implement?

as well.
Our engine renders entirely to a canvas, and for displaying
text we use the canvas text APIs. Since ~2012 we've had to
maintain our own custom word wrap engine in JavaScript to
handle multi-line text, and I doubt it does everything this
proposal does especially with regards to break opportunities
and bidi text, so it would be great if the browser could
handle that for us. I do think backwards compatibility would
be tricky though, as switching existing content to a different
word wrap engine will probably result in unwanted differences,
but there's not much that can be done about that.

Easily render multiline formatted text in Canvas, while
letting the browser handle the hard parts of line-breaking
and other language-specific constraints.

You have a paragraph of text. You want to write it to the
canvas. Canvas only supplies fill/strokeText-- only line
of text at a time. Where do you break your paragraph up?
Doing this is JavaScript is hard and error prone. For
example, the author must consider: where are the break
opportunities between words or Graphemes? Break
opportunities are based primarily on the Unicode Spec but
also use dictionaries for languages like Thai and French
that dictate additional line breaking rules. Other
considerationincludeidentifying grapheme clusters,
handling Bidi text, proper text shaping and kerning.
Luckily, the browser already has a powerful line breaking,
text shaping component used for regular HTML layout. This
feature enables authors to tap into the browser's layout
feature while maintaining control over the layout of
multi-line formatted text.

This feature exposes new functionality to the Canvas.
Similar behavior is being exposed to the CSS Houdini
Layout API. Our goal is to find a good balance in terms of
design that harmonizes the two concepts.
